The charge doesn't use the word accident to imply that the collision was unintentional. That's just the wording used in the Highway Traffic Act to describe any collision between a vehicle and anything else. It's perfectly valid to charge the motorist with the crime 'Assault with a weapon' and the HTA offence 'Leaving the scene'.
In any collision, the drivers are required to exchange insurance and identification information. Failing to do so for any reason (including running away from a crime) justifies the charge.
